• ✓ Water wisely by using drip or a watering can at the base and watering early so leaves dry quickly.
• ✓ Keep the area clean by removing plant debris at season’s end and sanitizing pots, trays, and tools.
• ✓ Improve drainage and avoid overwatering, especially for houseplants.
• ✓ Provide good spacing, prune to open the canopy, and avoid working among plants when foliage is wet.
• ✓ Mulch soil to limit splash and protect plants from frost and mechanical injury such as hail or rough handling, which create entry points for bacteria.
• ✓ Choose healthy starts and resistant or tolerant varieties when available, and rotate crops each year.
• ✓ Fertilize moderately and avoid excess nitrogen that encourages soft, susceptible growth.
